Abstract

Eine Prüfeinrichtung (1) zum Prüfen von Motoren (2), insbesondere von Verbrennungsmotoren, und zum Ermit­ teln von deren Betriebsverhalten enthält, um den Prüfling (2) wahlweise belasten oder antreiben zu können, eine an ein Stromnetz anschließbare und wahl­ weise sowohl im Generator- als auch im Motorbetrieb betreibbare elektrische Maschine (6) sowie ein im Über­ setzungsverhältnis verstellbares Getriebe (3), des­ sen Eingangswelle (23) mit einer Ausgangswelle (7) des Prüflings (2) und dessen Ausgangswelle (44) mit der Ankerwelle der elektrischen Maschine (6) gekuppelt ist, um die elektrische Maschine (6) unabhängig von der Drehzahl des Prüflings (2) immer im günstigsten Bereich betreiben zu können. Eine Steuereinrichtung (32) dient der Steuerung des Übersetzungsverhältnis­ ses des Betriebes (3) in Abhängigkeit von der Last­ situation des Prüflings (2), während eine Drehmoment­ meßeinrichtung (28) der Ermittlung des von dem Prüf­ ling (2) an der Ausgangswelle (7) abgegebenen oder auf­ genommenen Drehmomentes dient. A test device (1) for testing motors (2), especially of internal combustion engines, and for heating of their operating behavior to the DUT (2) can either be loaded or driven can, a connectable to a power grid and choice wise in both generator and engine operation operable electrical machine (6) and one in the over setting ratio adjustable gear (3), des sen input shaft (23) with an output shaft (7) of the Test object (2) and its output shaft (44) with the Armature shaft of the electrical machine (6) coupled is independent of the electrical machine (6) the speed of the test object (2) is always the cheapest To be able to operate the area. A control device (32) is used to control the gear ratio ses of the company (3) depending on the load situation of the test object (2) during a torque measuring device (28) of the determination of the test ling (2) on or on the output shaft (7) torque used.
